The effective potential is analyzed analytically by the help of Michel's conjecture'' and the result is confirmed numerically. We find that the E6 symmetry is spontaneously broken either to F-4 or to Sp(8) or G2 or SU(3), depending on which of the 4-fermi coupling constants G27 and G351 in the 27/351 channels is stronger. The possibilities for obtaining other type of breaking patterns are also discussed., text, application/pdf}, pages = {1217--1238}, title = {DYNAMICAL SYMMETRY-BREAKING IN AN E_6 GUT MODEL}, volume = {91}, year = {1994}, yomi = {サトウ, ジョウ} }
